Lag Spikes are spoiling my gaming

I have a deent 16Meg/1.5Meg 02 LLU connection which is very stable. When Im gaming I see lag spikes at random times. This has happened since switching from the O2 router to a Netgear N150. Is there a setting in the Netgear I need to change or something? Or could the Netgear be faulty?

The lag spikes happen at random times and last for 2 seconds at best. Speedtest.met shows now pakcet loss and 32ms ping to the best server for my region. Are there tools to help prevent lag?
 




Ping test results seem OK. I've pinged all my internal LAN devices and the results show 0 packet loss and a time of <1ms. This is really strange I'm kinda clutching at straws here. Would lowering the MTU size help?

I've not got direct experience with the N150 / WNR1000 or its interface so I'll take a bit of a guess based on the behaviour of some similar Netgear equipment.

Your problem could be down to the firewall dropping UDP packets due to what it considers to be a flood of data. Without on-time delivery of these packets the game client is unable to make positional updates and this can lead to momentary freezes and the distinct feeling of lag. Depending on the data rates used, you might find the problem is somewhat game specific.

I don't know if the N150 has varied settings which allow you to to differentiate between its 'proper' stateful (SPI) firewall functions and regular static packet filtering - the latter is actually what I'd suggest to disable as a test here but I think you'll have to turn the whole thing off.

To that effect, have a look around the web interface for an option to 'Disable SPI Firewall'.
 
Thanks for the advice ncjok, I can disable SIP ALG but thats to do with VoIP which I dont use. What about lowering the MTU size? and disabling port scan and dos protection?

Also under the NAT section I have an option to disable the firewall:

NAT (Network Address Translation)
Enable
Disable
Disable firewall

I've read its OK to disable the firewall if you are using NAT, is that true?
 
UPDATE:

I disabled port scanning and dos protection and the lag spikes not last about 1 second rather that 2 or more. Is there anything else I can do? I didn't have this problem when I was using the O2 Router

I have port forward applied to an assigned IP for the 360 (192.168.0.2). Set MTU to 1458 and disabled dos and port scanning in the router, what else can I do?
